IMPROVEMENT IN CLASPS FOR BRAlD-ROLLS.

Specification forming part of Letters Patent No. 93,487. dated July 24,1877 application filed May 31, 1877.

To all whom it may concern:

Be it known that I, JOHN UOGKCROFT, of Pawtucket, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements in Qlasps for Braidltolls and I do hereby declarethat the following specification, taken in connection with the drawingsfurnished and forming a part of the same, is a true, clear, and completedescription thereof.

It is well known that cotton-tapes and staybindings have for many yearsbeen put up for market in the form of rolls, and that clasps have beenemployed for securing the outer end.

Cotton fabrics of the character named are susceptible of being solidlylaid in the roll on accountof their comparatively inelastic nature, andtherefore a simple metallic clasp which embraces a few of the outerlayers may be and has been heretofore relied upon for securing the outerend; so also in this connection there has heretofore been used a pieceof elastic cord, which embraces one side of the roll.

Braid being loosely fabricated, and consequently elastic, cannot betightly laid in a roll without such a tension as would result in anundue reduction of its normal width, and this would seriously impair itsvalue for the uses intended; therefore a simple clasp which wouldembrace only a portion of the layers near the periphery of the rollcould not be relied upon for maintaining the roll in tact during theusage incident to the retail trade. The elastic cord, if of aserviceable tension, is liable to unequally contract the roll at itspoint of contact with the periphery, and, being elastic, it cannotperform any practical service in preventing the roll from being brokenby lateral displacement of the layers.

Prior to'my invention a wire loop has been successfully employed as aradial clasp .for braid-rolls, the said loop embracing one side of theroll by extending from the center to and across the periphery, thence tothe center on the opposite side. This last form of clasp beingnon-elastic does not contract the roll at the periphery, and its sidesafford a brace or support to the sides of the loosely laid roll,

and contribute largely to maintaining it intact, at least so far asone-half of the roll is concerned.

The improvements herein described relate to radial metallic clasps; andmy invention consists in a metallic clasp for braid-rolls,

which is provided with two or more arms, which radiate from the centerof the roll in different directions to and across the periphery of theroll, whereby the loose end of the braid is secured, and the side of theroll provided with a support.

'To more particularly describe my invention, I will refer to theaccompanying drawings, in which- Figure 1 represents a braid-roll withone form of clasp embodying my invention. Fig. 2 represents the claspdetached. Figs. 3 and 4 represent, respectively, a three and a fourarmed clasp.

A denotes the braid wound in the form of a roll. B denotes the simplest.form of my improved clasp. It is formed from a straight piece of wirewith a return bend, at a, which serves as a pivot or axis when the claspis placed on the roll. At each end is a rectangular bend, as at b, whichengages with the periphery of the roll, and an additional short bend, asat 0, which engages with the opposite side of the roll.

B denotes a clasp made of thin-rolled sheet metal, having three radialarms, which are provided wit-h the rectangular and return bends, asalready described, and a post at a.

B denotes a similar clasp, having four radial arms of the samecharacter, and an axial opening for encircling a wooden core.

It will be seen that either form of clasp will with one of its armsserve to secure the outer end of the braid.

Generally these clasps are employed in connection with a central woodencore, as at 01, although approximately valuable results may be attainedif no such core is used.

After the roll has been wound the clasps are readily applied by reasonof their flexibility.

Of course, I am aware that the number of arms may be variedindefinitely; and I do not 2 v HD3487 therefore limit my invention toany particular or more radial arms, which extend from the number, solong as there are two or more of center and engage with the periphery ofthe them which extend in difierent directions from roll, substantiallyas described.

the center to the periphery.

Having thus described my invention, I claim JOHN OOOKOROFT' as new anddesire to secure by Letters Pat; Witnesses: ent- DARIUS GOFF,

A metalllc clasp for braid-rolls, having two D. L. GOFF.
